It shouldn't take even a four-year-old to figure this out, but I will say it anyway… This article contains spoilers related to the ending of Paranormal Activity, if you have not yet seen the film and don't want to know anything about the ending then move along and wait until after you've seen it. Otherwise, enjoy.

For those that have already seen the movie you will remember the ending follows Micah's trip down the stairs as we hear Katie screaming in what is assumed to be the living room. There are some loud noises, followed by silence and then the steps that begin pounding up the stairs just before Micah's body is abruptly thrust into the camera lens and we see Katie's bloody body standing in the doorway. It's an absolutely fantastic ending that's followed by telling us Micah's body was found shortly thereafter, but Katie was not seen again. However, when the film first began making the rounds in 2007 things were a bit different.

Here's the original ending as detailed by Horror Squad's William Goss:

This time, Micah stays downstairs as Katie returns to the bedroom, covered in blood and now holding a knife. She proceeds to rock on the floor next to the bed for something like two days straight. We hear a friend (the girl who offered that Katie stay at her place, I'm guessing) leave a message on their answering machine, wondering where they are. She later stops by, presumably finds Micah dead downstairs, screams and leaves. The police then show up later, with Katie only awakening from her catatonic state as they come up the stairs, with guns drawn. She's covered in blood, holding a knife and very confused as to what's going on, and so the officers proceed to fire on her. The title card then dedicates the film to the couple's memory.

 Based on this description alone I personally enjoy the current ending a little better because I like the idea of Katie being out there still possessed by the ghost — even though this one has a definite creepy factor to it. Perhaps it would have been cool if after Katie threw Micah's body at the camera, she had walked in and sat down in a catatonic/possessed state for two days before going over to inspect Micah's body, as she does now, and disappearing forever. I don't know, just an idea.
